In terms of timed sports, such as bike races and running, even shaving mere seconds off a time could lead to breaking world records.

There are no rules in professional sports against taking caffeine unless in very high doses.

The safest level of caffeine consumption is 400 milligrams a day.

Going above the recommended consumption rate could lead to serious health repercussions.

The Mayo Clinic reported in 2006 that people who are at risk for heart attacks are increasing their chances fourfold after a cup of coffee.

Rob van Dam, an epidemiologist at Harvard University, previously said to Today, that coffee can increase cholesterol levels.

Overall, scientists are still debating how harmful coffee is to overall health because it has been linked to benefits as well.

Caffeine has been found to be a better replacement than over-the-counter pills to treat chronic pain.

Researchers from Boston Children’s Hospital in May found mice who had caffeine were more resistant to pain than those on painkillers.

Plus, coffee can lower the risk of developing liver cancer by a substantial amount, according to research from the University of Southampton in May.

Experts found people who drink just one cup of coffee a day are 20 percent less likely to develop the most common form of the disease.

Drinking two cups of coffee a day lowers the risk by 35 percent, while five cups cuts your risk of developing liver cancer in half.

The authors wrote: ‘It may be important for developing coffee as a lifestyle intervention in CLD (chronic liver disease), as decaffeinated coffee might be more acceptable to those who do not drink coffee or who limit their coffee consumption because of caffeine-related symptoms.’
